What issues?

This has nothing whatsoever to do with x86_64, it's exactly the same on F9

So what's the problem there?

But nspluginwrapper is used by default even on 32-bit installations for 
security reasons (because running the plugin in a separate process allows 
confining it with SELinux).

Or just don't use acroread at all, that's what Okular and Evince are for.

Konqueror can even embed Okular as a KPart if that's important to you.

I don't think this is related to 64-bit either.

So where's the problem?

OK, this is one valid argument. But the addons most people actually use should 
be available for x86_64.

I don't know how you ended up with all those conflicts. You should not need 
anything not in Fedora to get sound in WINE working. "yum install 
alsa-plugins-pulseaudio.i386" should be enough, and that drags in only stuff 
from Fedora.

This has nothing whatsoever to do with x86_64, it's exactly the same on F9

This is actually a good thing, not a problem. :-) In any case, it's not 
x86_64-specific either.
